vSpecifrcation of Letters Patent; Patented'ltllari 28,

Application filed March 20, 1920. sem No. 367,340.

To all whom it may concern:

Be it lznownthat 1, JOHN Ln; TUAL, a subect of the-hing of- Great Britain, residing at Montreal, Province of Quebec, Canada,

have invented certainnewand useful 1m provements in Machines for Removing Snow from Roadways; and I do'hereby declare that the following is 'a-full, clear, and'exact description of the invention, such as will enable others skilled in the artto which it appertainsto make and use the same.

The present invention relates toa newand improved machinefon the removal of 'snow from roadwa s and subsequently delivering the same intoa vehicle moving in unison with the machine. l

The principal object of the invention is to provide an apparatus for the=automatic removal of thesnow fromroadways streets or the like and having conveyingmeans for the disposalof'the same into vehicles.

Another object of the invention is'to provide an apparatus of the character described,

wherein the cutting elements and conveying frame are adjustable with respect to the road bed.

With the above an'dother objects in View which will hereinafter appear as the de-. scription continues, the invention consists of the novel features of constructiom combination and formation of parts as will be hereinafter-more fully described and particularly pointed out in the. appended claims;

In the accompanying drawings has been shown a simple and preferred form of the invention, it being however understood that no limitation is necessarily made to the p cise structural details herein exhibited, but the right is he'rebyreserved-to any changes,

alterations or modifications to which recourse may be had thatcome within vthe scope of the claims wi hout departing from the spirit of the invention or sacrificing the 'efi'ciencyof the same.

Figure iisaperspective view ofthe im- In apparatus for collecting and removing snow, hitherto devised it hasbeen customary to provide rotary plow elements mounted on a wheel supported frame and adapted to be forced into a mass of snow, or to pass over the road surface and cut the pack and throw the same aside by centrifugal force.

It is the purpose of the invention to'sup-' port the frame 10 upon the sled member 11, which latteris provided with runners 12. A bolt l3 connects the frame 10 withthe sled member 11 by which means the said flraine has-pivotal connection with the said s cc.

A conveyor frame 14, comprising the part'of the conveyor frame 14: adjacent the extremeend'has a shaft 17 extending trans versely therethrough, on theouter ends of which are mounted the star wheels 18 and 19 and which support-the apparatus at this point! These star wheels 18- and 19 are formed with the contact points 20 which bite into the roadway'surface whereby traction for the apparatus-is obtained.

Likewise the shafts 21 and 22 are mounted in the extremeendsof the; conveyor frame plates 15 and 1G'and carry therollers 23 and 24:.

Disposed within the conveyor frame 14 on the shafts 21 and 22 are the sprockets 25 26, 27 and 28:

The shaft 22 has its ends extending out- 'wardly beyond the side walls 15 and 16 of the frame 14. Keyed to said shaft ends are the gears29 and 30 which mesh with relatively large gears 31 and 32on the shaft 17 adjacent the star wheels 18 and 19. An apron comprising an endless wire screen passes over rollers 23 and 24 and extends the entirelength'of the conveyor frame 14.

Motion is imparted to the conveyor apron 33,13 7 the chains Stand 35, which are trained over the gears 26' and 29, and 25' and 28 respectively.

A rod 86-is secured to the lower end por tions of the side walls 15 and16. Hingedly mounted on said rod 36'is a cutting plate 37 provided on its outer edge with a series, of teeth or serrations.

V This cutting plate 37 is adjustable on rod 36 by means of the tangent bar 39 the upper end of which is formed with a rack 40 and the rack end of said bar 39 passes through a strap member 41 mounted on the side wall 15 of the conveyor frame 14. This strap member41 may be provided with teeth to engage the rack 40 of bar 39, whereby the cutting plate 37 may be adjusted to regulate the plane of the cutting teeth 39 with respect to the snow to be cut.

Likewise a vertically disposed plate 42 is suitably connected to the side wall 16 of the conveyor frame 14 and is formed with cutting teeth 43 disposed at right angle to the teeth 38 of cutting plate 37.

The function of plate 37 is to cut the surface snow from the roadbed, while that of plate 42 is to cutinto the heavier accumula tions; or drifts. r

A downwardly dire zed chute 44 is connected to the upper end of the conveyor casing 14 the function of which will be later described. 1 y

A plurality of wire cables 45 extend longi- ,tudinally of the apron screen and pass screen 33, the conveyor proper and as the over the transverse wire members 46 on which are mounted in staggered. relation the hooks 47 and the triangular studs 48. v

The hooks 47 and studs 48 form with the apparatus is drawn by animals suitably hitched to the draft, not illustrated, the'teeth 38 of the cutting plate 37Vwillbite into the surface snow. This snow when severed will be forced rearwardly upon the conveyor apron andv as the star wheels 19 and 20 are revolved by contact with the cross surface, the gears 31 and 32 on shaft 17, will actuate gears 28 and 29 on shaft 22. In this manner gears 27 and 29 on shaft 22 will be likewise actuated and in turn rollers 23 and24 will impart movement to the conveyor screens 33.

As the snow accumulates upon the lower end of the conveyor screen 33, it is held thereon by the hooks 47 and studs 48 and elevated with said screen and finally deposited into the chute 44. The chute 44 is dis posed downwardly and outwardly from the conveyor casing 14 and is formed with relatively vertical walls 58 and 59 and a divergent wall 60. These walls 58 and 59 together with the base portion 61 guide the snow downwardly out of the mouth49 of the chute and the snow drops by gravity into a vehicle arranged alongside of'the apparatus.

For elevating the conveyor casing 14, I

secure by bolts 50 the rack bars 51 to each side of the frame 10, while in the sled member 11 is mounted a shaft 52 carrying a gear Said shaft has its ends bent in such manner as. to form the crank handles 54 and over a pulley, not illustrated on the con.-

veyor casing 14 and its opposite end is connected to one of the runners 12.

The cutting plate 42 may likewise be capable of adjustment by means of the link connections 62 the ends of which are adapted to be inserted into the openings in the plates 58 connected to the side walls 15 and 16 of the conveyor casing 14.

It is obvious that the apparatus may be handled by a tractor or truck and is adapted for use in connection with the removal of snow from streets, roadways, sidewalks and the like.

' l-laving thus fully described my invention, what I claim as new and desire to secure by,

Letters Patent is V 7 V 1. The herein described apparatus comprising a sled, a framemember .pivotally mounted thereon, a gear carried by the sled, a crank for rotating the gear, and a rack carried by the frame member, and meshing with the gear, a conveyor carried by the frame, a blade at the lower edge of said conveyor, and side blades at the opposite sides of the conveyor, substantially as and for the purposes set forth. i

2. The herein described apparatus comprising a sled, a frame pivotally connected to said sled, a rack carried by the frame and extending beyond the sides of the sled, a gear journalled upon the sled and meshing with the rack, means for rotating said gear, a conveyor carried by the frame, a chute at one end of the conveyor, a fly-wheel carried by the frame for driving the conveyor, a blade adjustably connected at the forward end of the conveyor, and disposed in a substantially horizontal plane, means for tilting said blade, and a vertical plate attached to one end of said conveyor and cooperating with the blade, and means for swinging the conveyor upon the sled, substantially as and for the purposesset forth.

In witness whereof I have hereunto set my hand.

JOHN LE TUAL.
